While solar panels generate DC electricity, the grid operates using AC (alternating current) electricity. An inverter is needed to convert the electricity so that it can be used by the grid. A grid-connected system allows you to power your home or small business with renewable energy during. . Connecting solar panels to the electrical grid is one of the most effective ways to maximize your solar investment while maintaining reliable power.
